IMPRGVED SKATE.

@te .rlgrhule referat tu in there rttrts irtmt TO ALL WHOM-` IT MAY CONOERN:

s Be it known that IJOHN FORBES, 'of the city, county, and State of New York, have invented a newand useful improvement in Skat-es; and I do hereby declare that the following is a full, clear, and exact description thereof, whichv will enable others skilled in the art to make and use the same, reference being had tothe accom- Y panying drawings, forming part of this specification, `in which- Figure 1 is a side view of my invention.

Figure 2, a plan or top view of the same.

Figure 3, an inverted plan of a portion of the same.

Similar letters of reference indicate like parts. i t

This invention relates to a new and improved fastening for securing skates to the feet, whereby skates may with the greatest facility be flrmlysecured to the boot or shoe, and very readily detached from. it when required. The Yfastening is of that kind in which straps are4 dispensed with, and the skate clamped to the sole and heel of the boot or shoe.

A represents the .r'unner of the skate, which may be constructed in any of` the known forms, and B B are two posts or standards secured to the runner, one, B, near its front, and the other, B', near its rear end. To the front post B at its upper end there is secured, horizontally and transversely with the 'runner A, a guide# box, C, of oblong form, and composed cfa sheet-metal plate, (steel would be Vthe preferable material,) bent upward at its front and rear sides, and in this box two jaws, D D, are placed, andallowed to slide freely.

Thesejaws are also ofmctal, and of right-angular form, their lower horizontal parts being fitted in the bok C, and their upper or vertical parts serrated 'at their inner snrfaces, `so that they may grasp firmly the sides of the sole of the boot or shoe. The jaws D have each an oblong slot, a, made in their lower horiaontal parts, and similarslots, a', are made in the bottom of the'box C for bolts b to pass through, said bolts serving as guides for the jaws, and the bolts and oblong slots admitting of the jaws being adjusted further in or out, to suit the width of the sole of the boot or shoe to which the skate is to be applied. E represents a plate, which is secured by a screw or pivot-bolt, c, to the centre of the box C, and hasV two slots, d d, made in it, slightly curved, one inadvance, and the other in rear of the line of the screw or pivot-bolt c, (see iig. 2,) and heads e, which are on the bolts b, one fitted in' the slots d d. l

It will be seen from the above description that by turni-ng the plate E the jaws D D will be movedl simultaneously outward from and inward towards each other. The plate E isformed with an arm, F, which extends' towards' the rear of the runner, and is connected by .a bolt, with an arm, G, the rear end of 'which is made in circular form to fit into a corresponding-shaped recess i-n a sliding-plate, I'I, which is secured to a heel-plate, I, secured to the rear post B', thepplate I being provided with pendent pinsg-towork in oblong slots z'in the heel-plate, and serve as guides for the same. The front end of the plate H is bent upward,and provided with teeth j, projecting backward to 'penetrate the front side of the heel of the boot or shoe, while the rear end of the heel-plate I is provided with two fixed jaws, 7c lc, one at each side, against which the rear ofthe h ecl bears. When the arm F of the plate E is turned er moved to one side, as indicated in red in iig.` 2, the jaws `D D will be moved outward, and the plate H drawn forward, and the skate is then adjusted to the sole and heel of the 'boot or shoe when the -latter is on the foot of the wearer, and the'arm F is then shoved back directly ovel` and in line with the runner A, the rear endof arm F having a notchvmade in it to catch on the top of' the runner. This adjustment of, thearm F throwsthe plate I backward, so that the heel of the boot or shoe will be irmly clamped,whilc the jaws D D, being drawn inward, firmly grasp the sides of the sole. The Vplate I may .be adjusted further forward or backward, to suit the' sizeof the heel of the boot or shoe,ir 1 consequencev of having the boltf pass through an oblong slot, Z, in the arm F.`

The device is extremely simple, may be manufactured at a moderate cost, and there are no parts liable to get out of repair or become deranged by use.

Having .thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The slotted guide-box C, in which the slotted jaws D are adjustably secured and operated by means of the centrally-plvoted plate E in the concentric slots d of which lthe end of the bolts work, all constructed and operating as herein set forth for the purpose specified. j

2. The. combination and arrangement of the longitudinally-sliding plate H, slotted plate I,`ar1n G, and spring-arm F, pivoted slotted plate E, slotted jaws D, and'slotted guide-box C, as herein set forth for the purpose specied. l v

.IDI-IN FORBES.
